Dallas here from the Shopify Social Team.
I talked with our themes team and it isn't guaranteed that it will be able to be done. For something like that it would definitely need to be coded into the site. Since it is, however, a Shopify supported theme I will be able to send it up to our themes team to have them try and code that in for you.
I will send you an email to the account attached to this forum post. That way we will be able to be in direct contact. If you could reply back to that email from the account owner email on file I will send the request up to the themes department and have them work on that for you.
Since I can't make any promises, I wanted to give you the other option as well, and that would be to go to our Shopify Experts. They may also be able to get that done for you. Since I am not trained in code I am not able to make promises either way, but they are two avenues to look into.
